Jaspr Web 자동화 + Flutter Web 임베드 검증. CoUI Web 페이지를 점검하고, Web↔Flutter 듀얼 라이브 프리뷰를 구동하며, VM Service를 통해 로컬 Flutter Web 디버그 빌드에 연결합니다.
Web/Jaspr layer of the cocode verification stack. Covers two distinct needs that the VM Service-based MCPs (Marionette, mcp_toolkit, and the pixel-loop capture built on them) cannot:
Jaspr-rendered DOM — Production-built Jaspr SSG/SSR pages such as coui.cocode.im/components/*. Pure HTML/CSS; no Flutter, no VM Service.
Flutter Web embeds — Flutter widgets lazy-loaded into a Jaspr page (e.g. coui.cocode.im/live-preview-poc). In production this is a release-mode Flutter Web canvas — VM Service is
off, so only Playwright/Chrome DevTools work.
